⚒ The Hammer of Kum

Kagemaru finally finished his antics in the market square, the crowd cheering at his impressive ability to bend his body to impossible angles in every possible direction. He felt his cock tingle with excitement, wondering what kind of a new toy he should buy with all those coins now clinking happily in his pocket.

After wandering around for a while, his eyes fell on a beautiful red hammer hanging from a stall. It was adorned with intricate carvings and had an ornate handle that seemed to beckon him. The shape of this handle was so alluringly round and smooth, it made Kage's dick stiffen inside his tight fundoshi.

He ran back to his camp with the toy in his hands, eager to play with it as soon as he could. Throwing off his baggy kimono, he stretched out his naked body on his futon. With trembling hands, he slowly directed the tip of the hammer's handle towards his hole, unable to contain his urge any longer. He pushed forward, feeling the smooth metal slide effortlessly into his tight asshole.

"Ow f-fu-...!" He groaned with pleasure as he worked the handle deeper and deeper, each inch bringing him closer to ecstasy. The handle was so perfectly shaped for this, as if the hammer had been designed specifically for this purpose.

For a couple of hours, Kagemaru just couldn't stop himself from exploring the depths of his own ass with the hammer. Each orgasm sent shivers down his spine as the handle continued to probe deeper into his insides. His face flushed crimson when he realized that his buttocks finally touched the huge hammerhead, meaning he had actually taken every single inch of the handle inside!

But soon, an exhaustion took over. Still feeling some tingling sensations deep inside, he went to sleep, still holding onto the hammer tightly.

That night, Kagemaru had a vivid dream. In it, he found himself facing an enormous Oni, its horns piercing the sky, its teeth sharper than daggers and its cock bigger than a tree trunk. But instead of attacking him, the Oni treated him like a student and spoke words of ancient knowledge.

"This hammer," boomed the Oni, gesturing towards a strange weapon in Kagemaru's hands, "is no mere tool. It is the legendary Hammer of Ballsmashing, capable of granting incredible power to those who dare to use it."

Intrigued, Kagemaru stared at the hammer, wondering what the demon meant.

"If one were to smash their balls with this mighty instrument," the Oni continued, "they would gain unmatched strength and resilience. Your body will become nearly indestructible, your damage resistance exceeding that of the toughest armor."

He paused, his voice dropping low and sinister, "Your balls will grow to monstrous size, rubbery and unbreakable, able to withstand any hit without flinching!"

Kagemaru grinned, feeling a rush of excitement course through him. Without hesitation, he sat upon a nearby boulder and raised the hammer high above his head.

"Be warned, young warrior," cautioned the Oni, his eyes gleaming with mischievous light, "You must refrain from wasting your precious fluids. Accumulate as much as possible within your balls, then smash them flat with all your might! Only then will you unleash the true potential of the hammer!"

Kagemaru raised his eyes at the Oni, unsure about the perspective of never ejaculating again, wondering if it was even possible to hold back for even a few hours, let alone permanently. Masturbation seemed as natural as breathing to him; even thinking about it made him want to rub his cock right away.

"You must contain yourself!" yelled the Oni, sensing Kagemaru's apprehension, "Once you start smashing your balls with all your might, you won't give a shit about your puny human cumshots anymore! Trust me on this!"

With newfound determination, Kagemaru aimed for his crotch and brought the hammer down with all his might, but just before the impact, he suddenly woke up in cold sweat. He looked down at his groin and saw his testicles swollen and throbbing, pulsating with energy as if daring him.

His hand reached instinctively for the hammer lying beside him, its metallic surface cool against his warm palm. His heart pounded in his chest as he felt the urge building inside him, no question about what he had to do...
